so the expectation is that this is going to have significant impact. >> some of the images that we're playing next to you that we're seeing already coming out of there show that as well. what are your concerns for this happening in haiti? we just heard ed augustine say the country is in dire straits. we talked about the devastation from the 2010 earthquake, the political instability with the assassination last month of their head of state. what are you most worried about for the people there? >> i think it's just going to be very difficult to rebuild. this is a devastating event to occur. from a seismic, seismology perspective, we know that haiti has experienced large earth cakes in the past, not just the 2010 earthquake, but there have been significant earthquakes, in the 1700s, for example, that caused huge amounts of devastation. so, you know, it's a very seismically active area. the seismic expectation is that large earthquakes like this can occur. so yeah, we're just -- it's just a very devastating earthquake.
